Panorama to Tiny Planets

A quick panorama into the sun and then made into a ‘tiny’ planet.

Non-Compphoto

Last year I was in Sydney and after sunset on the pier; took a couple of pictures of the famous sunlit icons. I did not have a tripod so had to think about being creative;

This is a hold and zoom effect while taking a long exposure. Centred at the appropriate position and the only digital part was to rotate and crop the image for presentation.

The next two have varying exposure lengths – interseting to see the traditional effect on the waves.

Christmas Bauble – an aside

Actually this is from the eclipse in Australia in November: a little before last contact so partial eclipse is still in view.

Merry Xmas and Happy New Year.

Olympics Part 2

Second day was N3 (North Stand Tier 2) – first one previous post was in N1 (North Stand Tier 1). First was very close and direct contactt, whereas the N3 was like a high-def TV view.

This was Japan vs Egypt – in a crowded stadium (quarter-finals) it is difficult for good and large compositions. Thumbnnails below:

Large – about 123million pixels

Pictures from the Olympics

A couple of panoramas from the 2012 Olympics; Football: held at Old trafford (29/7/12)

• Egypy vs New Zealand
• Brasil vs Belarus

And of course you can do a 360 degree view from my seat – the rich people are behind me in the glass rooms.

Also an animated GIF – first time I have done this for ages. Lots of software to choose, but simpest was

• Align and crop using IrfanView
• Batch convert agin using IrfanView
• Finally used GIMP with each image as a different layer and then
• save as a gif with auto-cropping set and annimated mode

The Canon 7D has a high-speed capture mode to test out, so the wining goal by Brazil:

HDR fire

When taking HDR (High Dynamic Range) multiple pictures one thing you should not do is have moving components in the images. A quick test to prove this is shown at the recent firework day; where we had a large fire. Three pictures were taken,

and then HDR’ed together.

Taking standard image correction from the first raw photo gives a similar appearance – without the flame edge artifacts. Although, it does lose detail in the dark and lighht extremes.

Little Planets

Creating small wold effects from panorams.

I have seen this effect on posters and the process is very simple.

1. Take a panorama image – about 2.5:1 is about right
2. Resize the panorama images so it is square
3. Vertically flip the image
4. Then apply a polar coordinate filter – available in GIMP and photoshop
5. Rotate image and blend edges as is aesthetically appropriate.

So an example from Manchester city centre.

Panorama is from near the City Library: nice mixture of architectural style. This image is made from 35 images creating a panoram that is 11,374 x 4,161 pixels. It was done hand-held with some artifacts.

Next make this image square – in this case creating a square image 4,500 x 4,500.

Then vertically flip

and polar coordinates transform

a bit of cropping focusses the distortion.

and not vertically flipping creates a reverse operation.

Futureversions  could do with having HDR images as outside and better aligned panorams.

 

Panoramas from SIGGRAPH

These were quick snaps from Vancouver and the SIGGRAPH village. No pictures of the exhibition space nor the gallery installations – you will just have to attend next year.

A little experiment – frst take a normal panorama of the village space, which was done on the initial set-up day with 16 different pictures.

Now if you rotate all the images the same panorama code tries to create a 90 degree panorama, with a different effect.

So we have a different perspective on things. A more conventional view with customers. on the next day at the village

A couple of view outside the Vancouver Convention Center. Note panorams don’t have to be long and thin.

And another one with the images individually rotated.

First GigaPan Image

My first GigaPan image is now uploaded – this blended 275 images. In my opinion this is justified as GigaPan image as the resulting resolution is a bit larger than 2 Giga-Pixels.

There were a few failures before this and smaller test imagess.

Stereoscopic Image Creation

Muttyan runs a great set of utilities for alining stereo images.

A few sculptures from around the University of Manchester. Shown are cropped left -right pairs which need focussing behing the screen, in a similar manner to the magiceyes images. Follwing is a anaglyph – red-cyan glasses.
